Application February 17, 1956, Serial No. 566,144

1 Claim. (Cl. 292-192) The present invention relates to doorholders, and more particularly to doorholders which are attached to the door and used for maintaining a door in open position.

The primary object of the invention is to provide a doorholder which is resiliently urged against the floor and which can be disengaged by movement of the door.

Another object of the invention is to provide a doorholder which can be clamped in a position of rest.

A further object of the invention is to provide a doorholder which can be brought into door holding position by slight movement of the door after the doorholder is engaged with the floor.

A still further object of the invention is to provide a door holder of the class described above which will be inexpensive to manufacture, simple to use, and positive in its action.

Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings, in which:

Figure 1 is a front elevation of the invention shown attached to a door with the door partially broken away.

Figure 2 is a side elevation of the invention, partially broken away and partially in section.

Figure 3 is a vertical cross-section taken along the line 3-3 of Figure 1, looking in the direction indicated.

Figure 4 is a horizontal cross-section taken along the line 4-4 of Figure 1, looking in the direction indicated.

Referring now to the drawings in detail wherein like reference numerals indicate like parts throughout the several figures, the reference numeral indicates generally a door to which the invention is attached. A floor 11 is positioned beneath the door 10 in spaced relation thereto. A door stop generally indicated at 12 consists of a rectangular housing 13 having a pair of parallel side walls 14 and 15 which are joined by a rear wall 16, and a front wall 17. The rear wall 16 and the front wall 17 are parallel to each other. The walls 14, 15, 16 and 17 are joined at their upper ends by means of a top wall 18.

An car 19 extends upwardly from the top wall 18 in alignment with the rear wall 16. An ear 20 extends laterally from the side wall 14 in alignment with the rear wall 16. An ear 21 extends laterally from the side wall 15 in alignment with the rear wall 16. The ears 20 and 21 being positioned medially of the upper and lower ends of the side walls 14 and 15, respectively. A resilient clamp 22 is secured to the lower ends of the front wall 17 by means of rivets 23. The spring clamp 22 is provided with a pair of outwardly extending resilient arms 24 and 25 which carry inwardly ofiset end portions 26 and 27, respectively. A rectangular body 28 is mounted Within the housing 13 and adapted to reciprocate vertically therein. The body 28 is provided with a spring receiving recess 29 in its upper end and a coil spring 30 has one end thereof seated in the spring recess 29 and the other end thereof engaged against the underside of the top wall 18 whereby the body 28 is resiliently urged toward the lower end of the housing 13. The lower portion of the body 28 is ofiset at 31 providing a shoulder 32 adjacent the rear wall 16 of the housing 13.

A retainer 33 is secured to the lower inner edge of the rear wall 16 by means of retainer elements 34 cooperating with the shoulder 32 to retain the body 28 within the housing 13. A rectangular foot 35 is positioned as an extension of the body 28 and pivoted thereto by means of a hinge 36. The lower end of the foot 35 carries a bulbous extension 37 over which is mounted a rubber floor engaging cap 38, as best illustrated in Figure 3. The housing 13 is secured to the door 10 by means of securing elements 39 which extend through the cars 19, 20 and 21.

In the use and operation of the invention, the doorholder 12 is normally positioned as illustrated in Figure 2 with the foot 35 secured in elevated position by means of the spring clamp 22. When it is desired to maintain the door 10 in open position the foot 35 is moved to the dotted line position as illustrated in Figure 2 by pulling it from the clamp 22 and releasing it so that it can engage the floor 11. The door 10 is opened as wide as desired and then moved slightly toward its closed position. Upon movement of the door toward its closed position, the rubber cap 38 binds against the door 11 causing the body 28 to move upwardly in the housing 13 against the pressure of the spring 30 permitting the foot 35 to swing to the position illustrated in Figure 3. The spring 30 will maintain pressure against the cap 38 so as to keep it in frictional engagement with the floor 11 as long as the door 10 is not moved in either direction.

When it is desired to close the door and release the doorholder 12, the door 10 is swung away from closed position which causes the foot 35 to pivot on the hinge 36 to a position such as is illustrated in dotted lines in Figure 2, whereupon the foot 35 is lifted by hand and pressed into the clamp 22 where it remains until again needed.

Having thus described the preferred embodiment of the invention, it should be understood that numerous modifications and structural adaptations may be resorted to without departing from the scope of the appended claim.

What is claimed is:

A doorholder comprising a housing, a body vertically slidable in said housing, said body projecting from the lower end of said housing, resilient means biasing said body toward the lower end of said housing, an elongated foot, pivot means securing said foot to the lower end of said body, said foot being movable about said pivot means from a floor contacting position to a storage position spaced from said floor, means on said housing for maintaining said foot in said storage position, means on said housing limiting the movement of said body therefrom, and a resilient floor engaging cap member detachably secured to the lower end of said foot, said foot being adapted to cam into alignment with said body by moving said body upwardly against the tension of said resilient means.
